TEMPERATURE-REGULATOR.

To all whom it may concern:

Be it known that I, LEVIN D. VAUGHAN, a citizen of'the United States, residing at Philadelphia, in the county of'Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Temperature-Regulators, of which the following is a specification.

My invention relates to an improved mechanism to be applied to boilers, hot water heaters and the like, for the purpose of automatically putting on, or shutting oil, the draft at a predetermined time. The objects of the invention are the provision of a temperature regulator operated and controlled by means of a clock mechanism in combination with my expansion and contraction temperature regulating device, for which Letters Patent were issued to me liar-ch 27th, 1917, No. 1,220,381, this present application being a division of the original application therefor, which is simple and durable in its construction and which will operate in a positive manner to control the draft and regulate the fire and such other and further objects as may hereinafter appear.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings in which- Figure 1 is a front view of a boiler with my temperature regulating device in place and my present device connected thereto;

Fig. 2 is asectional view illustratin the clock mechanism;

Fig. 3 is a detail view of the trigger or trip mechanism in engagement and Fig. 4- is a detail view of the trigger Or trip mechanism out of engagement.

Similar reference characters refer to similar parts throughout the drawings.

Referring to said drawings the numeral 10 represents a pipe connection to a boiler, or source of water supply, said pipe being threaded on its upper portion to receive a Y shaped joint 11. One angle of said Y shaped. joint 11, being a continuation of the water supply, by means of the pipes 15 and 16 carries the water to the radiators.

Secured to the upper part of the other angle of said Y shaped joint 11 is a bushing 01 member 4'? which acts as a support for Specification of Letters Patent.

Patented Feb. 5, 1918.

Divided and this application filed May 24.

the saddle or yoke at), said member i7 at its center of height being hexagonal. The yoke- 413, n'ojccting laterally 'up'on opposite sides of the piston rod guide and havdngupwardly extending arms 12 and secured thereto by lock nuts as illustrated, is fastened to the bushing l7 also by means of lock nuts. The upwardly extending arm 12 is bifurcated at its upper end to receive loosely the lever 14, which in this instance is a horizontally disposed beam, pivotally mounted, at an intermediate point, upon a pin 13*. The upwardly extending arm 45 is-slit to act as a guide for said lever 14 and to allow free play thereof. Adjusting nuts 12 are threaded on the upper end of the piston rod 13, as illustrated. The lever 14 has'a-ttached thereto in any suitable manner the weight 17. A flexible chain or cord 37 is secured to an opening in the 1ever 14 and extends down and is fastened to a ring on the ash pitdoor 38 as illustrated. Also secured to an opening in said lever 14 are the connections 18 and 19 to the flue damper 20" as shown.

ln'my former application, on which Letters Patent were issued, as hereinbefore set forth, I have described in detail my method of regulating temperature by means of expansion and contraction in conjunction with the mechanism just described. I now describe nuy clock mechanism in combination therewith to regulate the temperature by a time control.

A box or casing 31 is provided, one side thereof, 30, being of glass in order that the operator may see the face of the clock 32. An alarm clock 32 of any suitable make is placed in the bottom of said box or casing 31 and is securely held in position there by means of the strap 33 which is secured to the bottom of the casing by means of nuts 36. Said strap is adjusted by means of the buckle 33.

A chain or cord 21 secured to an openin in the lever It and passing over the guide pulleys 22 and 23 as illustrated and through an opening in the top of said casing 31, terminates in the ring 44. A bracket 29 is bolted to the inside wall of the casing 31 as illustrated and the trigger or trip member is bolted thereon, by means of nut A guide pulley 25 is secured to the under part of the upper portion of the casing 31 and a cord 26 passes over said pulley as shown, one end thereof being secured to an opening in a lever 27, said le er 27 being secured to the bracket 29 by the nut 28 as illustrated. The other end of said cord 26 is secured to a catch. or hook member 34, which is hooked to the alarm winding key 35, on the back of the alarm clock 32.

The lever 27 is secured to bracket 29 by means of the nut 28 and is provided with a notch 8 at its free end to engage the trigger 49.

Briefly the operation of my clock mecha nism is as follows:

The operator sets the alarm of the clock for a predetermined time. The i'neinber is hooked to the alarm winding key 35, and the ring 44 on chain 26 is slipped over trig ger 49, which is placed in engagement with the lever 27 this tightens up cord 26 and pulls up the weighted lever 14.

This action of the lever 1a closes the ash pit door 38 and the damper 20 in the flue.

When the predetermined time comes the alarm operates revolving the key winding member 35 which releases the hook 34:. This action releases the trigger 49 from engagement with the lever 27, thereby freeing the cord 26 which allows lever 14: to return to its normal position. This action opening the ash pit door 38 and the damper 20 in the flue.

I do not restrict myself to the exact details oi construction, combination and arrangement herein set forth, it being obvious that minor variations thereof not involving the exercise of invention may be made by the skilled meclnn'iic and such de tiarture from what i ha \0, herein described and claimed not involving invention I consider as within the scope and terms of my claim.

Having thus described my invention what is clain'ied as new and desired to be secured by Letters Patent is:

In a. device of the character described, a clock provided with an alarm. winding key and means connected thereto, comprising a cord passing over a guide pulley, secured to an opening in the free end of a lever a lever, means for engaging said lever with a trigger, the other end of said cord terminatingin a catch member adapted to hook on said winding key whereby when said winding key revolves said catch member and said lever are released from engagement with said winding key and said trigger respectively, substantially as shown and de scribed.

In testimony whereof I afiix my signature in presence of two witnesses.
